yes... but... babylon 5 with some holy light guys set in warzone??
the world is not overrun with shadow ships and angels to counter them.
its zombies, dark technology, madness and warzones around citadels with 1. ww mass battles..
angels would not fit, not even a "pure good" side.
the world is in my feeling different, more dark, gritty, heroic and desparete.
not so much "religiouse" in an angel/devil seting. its there, with the brotherhood, but they are like zelots and not like the "good" guys.
-> no good side, no tau please (jeah, imho
)
